2.A the following reaction is a balanced reaction for the combustion of ethane: 2C2H6(g) + 7O2(g) -> 6H2O(g) + 4CO2(g)

if 5.00L of oxygen gas are used in the reaction, and the react occurs at SATP condition,

2.B what volume of carbon dioxide is expected to be produced?

what mass of carbon dioxide is expected? (Determine this using molar volume, not PV=nRT

Agas is contained in a thick walled balloon when the pressure changes from 1.21 atm to 2.52 the volume changes from 3.75 l to 1.72 l and the temperature change from 293k to blank k

Based on its chemical properties, identify the position of each chemical family on the periodic table.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
